Compile and run it

git clone https://github.com/dennis/hello_go
cd hello_go
go build main.go
./main

Using it via Docker

To build the image and start it:

docker build -t hello_go .           
docker run -p "8080:8080" hello_go

Using the service

The service does not persist any data, so any changes are only effective while it is running. Credentials are hardcoded in source, so ther is no security either.

The services is pre-populated with two messages. One from each user.

Authentication

The service requires basic authentication on all requests. Use authtokendennis or authtokenmarianne for this. This is a token, so there is no password

Via postman

For you convience I've created a collection for Postman, you can import the collection and configure a api_token variable (I suggest you do it via the environment). It needs to be either authtokendennis or authtokenmarianne.
